The Battle of (the) Trebbia (17–20 June [O.S. 6–9 June] 1799) was fought near the rivers of Tidone, Trebbia, and Nure in northern Italy between the joint Russian and Habsburg army under Alexander Suvorov and the Republican French army of Étienne-Jacques-Joseph-Alexandre Macdonald. Though French forces were moderately more numerous, the Austro-Russians severely defeated the French using the oblique order tactics, sustaining about 5,500 casualties while inflicting losses of 16,500 on their enemies. The Russian contingent was on the right flank of the coalition force and in the center, and it was the Russian units that played the main attacking role; the Austrians dealt with the French on the left flank, and they helped the Russians in the center. The War of the Second Coalition engagement occurred west of Piacenza, a city located 70 kilometres (43 mi) southeast of Milan. In the spring of 1799 the Habsburg and Russian armies ousted the French from much of northern Italy after the battles of Magnano and Cassano and they placed the key fortress of Mantua under siege.
